Detailed Description
template<typename _IntType = int>class std::uniform_int< _IntType >
Uniform discrete distribution for random numbers. A discrete random distribution on the range $[min, max]$ with equal probability
throughout the range.

Member Function Documentation
template<typename _IntType = int> result_type std::uniform_int< _IntType >::max () const [inline]
Gets the inclusive upper bound of the distribution range.
Definition at line 1592 of file tr1_impl/random.
template<typename _IntType = int> result_type std::uniform_int< _IntType >::min () const [inline]
Gets the inclusive lower bound of the distribution range.

template<typename _IntType = int> template<typename _UniformRandomNumberGenerator > result_type std::uniform_int< _IntType >::operator()
(_UniformRandomNumberGenerator &__urng) [inline]
Gets a uniformly distributed random number in the range $(min, max)$.
